We used observed parenting behaviors, along with genetic variants and haplotypes of the serotonin transporter gene (SLC6A4), as predictors of children's ego‐resiliency during early childhood (N = 153). The quality of mothers' parenting was observed at 18 months of age, and mothers' reports of ego‐resiliency were collected at six time points from 18 to 84 months. Genetic data were collected at 72 months. Observed parenting was positively associated with initial levels of children's ego‐resiliency. Furthermore, although individual genetic variants of the serotonin transporter gene (LPR, STin2) were not associated with ego‐resiliency, the S10 haplotype (that combines information from these two variants) was negatively associated with initial levels of ego‐resiliency. Both parenting and serotonin genetic variation uniquely predicted children's ego‐resiliency, suggesting an additive effect of genetic and parental factors.  相似文献

Organisations providing human services are under increasing pressure to demonstrate quality from a range of sources such as new legislation and new requirements for government funding. Four dimensions for examining quality, derived from program evaluation theory, illustrated some of the contradictions surrounding these expectations. The research used a qualitative and grounded approach to exploring clients', volunteers' and coordinators' notions of quality service. The clients' and volunteers' perceptions of quality were highly experiential, related to the specific context and focussed on strong trusting personal relationships. Clients were also very conscious of their lack of power. Coordinators used a combination of approaches to try to satisfy the demands of clients, volunteers and bureaucracy.  相似文献

Twenty years ago, the National Institute of Child Health and Human Development (NICHD) issued a request for proposals that resulted in the National Survey of Families and Households (NSFH), a unique survey valuable to a wide range of family scholars. This paper describes the efforts of an interdisciplinary group of family demographers to build on the progress enabled by the NSFH and many other theoretical and methodological innovations. Our work, also supported by NICHD, will develop plans for research and data collection to address the central question of what causes family change and variation. We outline the group's initial assessments of orienting frameworks, key aspects of family life to study, and theoretical and methodological challenges for research on family change. Finally, we invite family scholars to follow our progress and to help develop this shared public good.  相似文献

Objective. Why do some firms participate in voluntary programs earlier than others? What conditions dictate whether firms participate in voluntary programs earlier rather than later? Current research on voluntary programs has not considered discrete processes in which corporate actors could have different motives and objectives in different time dimensions, that is, early versus late. Methods. We adopt a diffusion theory to disaggregate corporate voluntary participation behavior in the Environmental Protection Agency (EPA) sponsored Green Lights (GL) voluntary program. We focus on the GL participants during two periods—the early joiners in 1993–1994, and the late joiners in 1995–1996. Results. At the early diffusion stage, firms are more likely driven by the market motive that garners a “green” reputation, an important strategic asset to promote market competitiveness; at the late diffusion stage, firms are more driven by the institutional motive to improve their relationships with regulatory agencies and subsequently relieve regulatory pressures from them. Conclusion. We find that firms have different motives for GL participation at different diffusion stages. We suggest that policymakers who want to induce firms to join voluntary programs should pay more attention to program designs and implementation schemes that accommodate different corporate interests and objectives in different time orders of firms' participations in voluntary programs.  相似文献

Objectives. The objective of this article is to analyze the mobilization factors available within and without international factories that do and do not contribute to political participation of employees, hypothesizing that the quantity, type, and causal linkages will vary by gender. Methods. Using original survey data of factory employees (N=402) in multiple sectors and regions in Mexico, I test common explanations as to how the factory experience stimulates and stifles the political participation of women employees, exploring whether the causal linkages between the workplace and political engagement are the same for women and men. Results. Contrary to some of the recent research that reveals men to be more politically engaged than women in the Mexican population overall, my data show that among factory workers there is rough parity between men's and women's levels of political engagement. A distinction of note, controlling for other variables, female employees are more likely than male employees to engage in informal political activities. Conclusion. The international factory experience appears to have a limited “egalitarian” effect. The distribution of factors leading to political mobilization for women and men is not equal, yet women are able to translate a distinct set of factors into participation.  相似文献

We introduce an extension of the Esteban and Ray [Econometrica, 62:819–851 1994] measure of polarization that can be applied to density functions. As a by-product we also derive the Wolfson [Am. Econ. Rev., 84:353–358 1994] measure as a special case. This derivation has the virtue of casting both measures in the context of a (statistically) unified framework. We study the polarization of the distribution of household income for five OECD countries (LIS database): US, UK, Canada, Germany and Sweden. The present paper is essentially based on Esteban, Gradín and Ray [9], published as #218 in the working papers series of the Luxembourg Income Study. Changes have been kept to a minimum. We have provided a brief reference to the literature on polarization measurement that has appeared since then and have updated the data of our application.  相似文献

This study analyzes the associations between marital status, gender, and depressive symptoms among parents. The regression results indicate that married parents report fewer traditional depressive symptoms and lower rates of alcohol abuse than do single parents. Mothers and fathers also appear to be more likely to exhibit different depressive symptoms: Mothers are more likely than fathers to report traditional depressive symptoms and fathers are more likely to report the abuse of alcohol. Finally, we find evidence that indicators of parenting burdens such as economic strain, household labor, childcare, social support, and religious involvement mediate and moderate these relationships.  相似文献

This paper explores how contradictory social structures influence power relations between “Vietnamese brides” and their Taiwanese family members. By analyzing two aspects of interaction between “Vietnamese brides” and their husbands’ families, i.e., how the families require them to integrate into Taiwanese society and what strategies they employ to escape from these constraints, we argue that contradictory social relations together with commodified marriage and liminality help them to develop strategies of escape into the “hidden space.” The development of these strategies indicates one thing: hegemony is never fully achieved – it is always negotiated and contested.  相似文献
